Keep the Crusts On!
This is the study of Earth's physical structure, its history/processes and the composed rocks.
What is Geology?
This makes up the upper part of the mantle and the crust above.
What is the lithosphere?
Decayed remains of once living creatures.
What is Humus?
This is found uphill from the alluvial plain, possibly formed when sea levels are higher.
What is a coastal plain?
This occurs when rocks are broken down by ice, water, wind or temperature changes.
What is weathering?
This is made of solid rock and the only layer we have been able to explore.
What is the Earth's Crust?
The Earth's lithosphere is broken up into pieces called these.
What are plates?
inorganic crystalline substances found naturally in the Earth.
What are minerals?
This is formed when glacial sediment is left behind in glacial melt.
What is a glacial plain?
The process of wearing or grinding something down by wind, water, or other natural agents.
What is erosion?
Earth's crust is divided into two types, Oceanic and...and it is made up of what?
What is the Continental Crust? What is granite?
The boundary where two plates meet.
What is a fault?
Sedimentary and Igneous Rock can form this.
What is Metamorphic Rock?
This is formed when a crack in the crust doesn't reach the surface, but accumulating magma bulges up the crust.
What is/are domed mountain(s)?
The chemical composition of the rocks in this type of weathering does not change.
What is physical weathering?
This is the middle layer of earth and right below the crust.
What is the mantle?
This sits below the lithosphere and above the outer core.
What is the asthenosphere?
Magma is below the surface, but when we can see it, it's called this.
What is lava?
This forms when 2 moving rock masses push against each other, buckling the crust into an up-and-down rolling pattern.
What is/are folded mountain(s)?
This affects rocks by reacting with minerals inside them.
What is oxygen?
As we go deeper into the Earth these get higher and this is greater.
What are the temperatures and the pressure?
This theory holds that much of the movement of Earth's plates occurred rapidly.
What is the Catastrophic Plate Tectonic Theory?
Sedimentary Rock transformed is called...
What is limestone?
At a greater temp/pressure:
What is marble?
